摘要

The primary objective of this research is to develop in-situ processes to join thermoplastic composites to metals in net-shape processes. A hot-melt process and compression molding process will be used as model environments. The surface preparation, contact pressure during consolidation, heating and cooling rates, hold times at melt and recrystallization temperature, effect of bond line thickness and uniformity, and anodization to increase durability will be included in the process development cycle. The results will then be applied to filament winding and injection molding and optimized using the models concurrently with experimental characterization. Induction heating will be incorporated to increase the process speeds, reduce polymer residence time at melt, and make the process attractive for applications. By selecting three diverse non-competitive industries, namely bio-medical, aerospace and automotive, major reduction in assembly, tooling, and processing costs by reducing the times and steps to manufacture may be seen in applications such as bio-medical implants, suspension linkages, airframe structures, and metal bearing sleeves.rnAt the teaching front, a new curriculum that integrates design and processing will be developed. A synergistic combination of engineering fundamentals, hands-on, modeling, multi-media, inter-disciplinary experiences and industrial perspective will be used. A new course "Design for Processing" (DFP) will be developed to make strong linkages between design and processing alongside with a "Virtual-Processing Laboratory" (VPL).
